[Continued] The other issue is command interception, such as with Lisp. It is very awkward to have to Undefine commands to provide interception; one would have undefine numerous commands to provide any kind of usable features, such as AutoSaves or intercepting the Plot command to update a Drawing Management attribute. I could probably think of dozens of uses for such a feature. One last beef… Why in the world does a PLOT command disable the Undo History?! There are many times that I want to plot a divergent scheme and then go back (without having to maintain a series of Wblocked files). It is funny that UNDO will go back past a SAVE or WBLOCK, but not a PLOT. I was really baffled by why one could not do this. Is the PLOT command so separate from the rest of the program that it disables the link? Or is the assumption that if one PLOTs, they would never want to go back <smirk>?! FWIW, thanks for your interest and patience in letting me vent some spleen! Brian Boatright
